Piece of the Sky in PPG

The closest PPG paint to Vista Paint Piece of the Sky (7304) is American Anthem 1156-4, a delta-E of 1.85 away — close enough to swap without anyone noticing, though a large sample in daylight will show the difference.

American Anthem is 3 LRV points lighter, so the room will read slightly brighter. Undertone reads as blue against blue, at chroma 16.2 and 18.0.

Codes are not transferable between manufacturers and no brand publishes a conversion table, so every figure here is measured from the published hex values rather than taken from a chart.
